Fighting against Tablebases ...

... is like fighting against windmills (as Don Quichote did)! Why is is so hard for some very good chess players here on FICGS, to accept their looses, to resign and to congratulate their oppenent?

Fighting against Tablebases

Hello Wolfgang, please remind me (here or in our games) the game you're talking about. Quite strange that shredderchess tablebases did not give the same result than yours.

Anyway, if your opponent does not have 6-pieces tablebases and his engines and instinct say +0,70, it may be hard for him to trust you :)

Best, Thibault

#3724 : I would be surprised at any engine, which cannot see the mate (in 37) after few seconds (with installed 5-pieces Tablebases)!

Tablebases 5-pieces

Well, quite strange.. Shredderchess.com tablebases don't give a result anymore for the current 7-pieces position !? .. Was it a bug or...

Indeed it is mate in about 37 moves, but my engine with 5-pieces tablebases can't see it. If the game is not finished in a while (before the next rating calculation), you can call referee for adjudication.

Tablebases 5-pieces

Thibault: Not about, but accurate mate in 37! What is wrong with your installation - I'm not longer wondering, why you can't win against me! ;)

Needing over a terabyte of disk space, I doubt if anyone actually has the 6 piece tablebase installed on their computer, though a position can be queried at:

BTW, I've played endgames here where I had to play the game out to checkmate where my opponent had just a king and a few locked pawns, while I had an advantage of a queen, rook, and several extra pawns.

Problem is solved

- time has run out. With the great behavior of a real sportsman my opponent abandons to resign in a normal way. ;( Further on I will abondon to play against him over again.
